TRIAD Cluster


To modernize information dissemination the Public Transportation (PT) and Surface Transportation (ST) ISACs, in collaboration with American Public Transportation Association (APTA), and the Association of American Railroads (AAR), and the Transportation Security Administration (TSA) developed the Transit and Rail Intelligence Awareness Daily (TRIAD) Report and associated Transportation Information Library.


The TRIAD is developed from the numerous sources of intelligence available to the Transportation community today, focusing on counter-terrorism, suspicious activity reports, general security awareness and cyber security. The Surface Transportation Security Information Library, available to those vetted to receive the TRIAD, acts as an information repository, housing all sources of information provided in the TRIAD as well as other security products, information reviews, and intelligence not provided in the TRIAD. The information serves as a resource for future research into threats or mitigation techniques.
